GOST 34.10 is Russia’s DSA. Just as it’s U.S. counterpart, GOST is an ElGamal like signature scheme used in Schnorr mode. It is close to NIST DSA in many aspects. In our paper we will first overview GOST 34.10 and discuss the three main differences between the two algorithms. – GOST’s principal design criterion doesn’t seem to be computational efficiency: The algorithm is 1.6 times slower than ...

GOST 28147-89 is a well-known block cipher and the official encryption standard of the Russian Federation. A 256-bit block cipher considered as an alternative for AES-256 and triple DES, having an amazingly low implementation cost and thus increasingly popular and used [12,15,13,20]. Until 2010 researchers have written that: “despite considerable cryptanalytic efforts spent in the past 20 years...

This document provides information about the Russian Federal standard for digital signatures (GOST R 34.10-2012), which is one of the Russian cryptographic standard algorithms (called GOST algorithms). Recently, Russian cryptography is being used in Internet applications, and this document provides information for developers and users of GOST R 34.10-2012 regarding digital signature generation ...

GOST R is the hash function standard of Russia. This paper presents some cryptanalytic results on GOST R. Using the rebound attack technique, we achieve collision attacks on the reduced round compression function. Result on up to 9.5 rounds is proposed, the time complexity is 2 and the memory requirement is 2 bytes. Based on the 9.5-round collision result, a limited birthday distinguisher is pr...

In this paper, we present a related key truncated differential attack on 27 rounds of XTEA which is the best known attack so far. With an expected success rate of 96.9%, we can attack 27 rounds of XTEA using 2 chosen plaintexts and with a complexity of 2 27round XTEA encryptions. We also propose several attacks on GOST. First, we present a distinguishing attack on full-round GOST, which can dis...

GOST-R is a Russian Standard Cryptographic Hash function which was first introduced in 1994 by Russian Federal for information processing, information security and digital signature. In 2012, it was updated to GOSTR 34.11-2012 and replaced older one for all its applications from January 2013. GOST-R is based on modified Merkle-Damg̊ard construction. Here, we present a modified version of GOST-R ...

GOST 28147-89 is a well-known Russian government encryption standard. Its large key size of 256 bits at a particularly low implementation cost [77] make that it is widely implemented and used [66, 96, 62, 77, 82]. In 2010 GOST was submitted to ISO to become an international standard. GOST was analysed by Schneier, Biham, Biryukov, Dunkelman, Wagner, various Australian, Japanese, and Russian sci...

The former Soviet encryption algorithm GOST 28147-89 has been standardized by the Russian standardization agency in 1989 and extensive security analysis has been done since. So far no weaknesses have been found and GOST is currently under discussion for ISO standardization. Contrary to the cryptographic properties, there has not been much interest in the implementation properties of GOST, thoug...
